Fuel Tank cleaning Options

[Rusty]

I've got minor surface rust on the interior of my fuel tank. Since I'm pulling the tank out for other maintenance, I might as well handle this too.

Any thoughts on the best way to handle this job? I know there is some controversy about the Eastwood/POR kits.

thanks,
Rusty

I just did this over the past week. Mine had quite a bit of rust. What I did was take mercuric acid and water with a 50/50 ratio. I used a gallon of MA. Then shook the the daylights out of it. Then let it set 10 to 15 mins per side. Poured it out and washed out the take with water. It removed a lot of rust. Then I purchased a fuel tank sealer kit off of Amazon. I reflushed it again with the cleaner to get any additional rust, let dry. Poured in rust prohibitor and shook it around. Poured out and let dry. Then put almost 2 quarts of sealer and let dry for a few days. It is not a quick process. Takes a few days to do it right. Mine turned out great. Like I said, I had a lot of rust. Be sure to treat any outside rust as well if you have bubbling.
